I was newly diagnosed with ductile carcinoma.

Can you tell us a little bit more about your situation? What kind of details do you have about the cancer, and about a proposed treatment plan? What kind of surgery has been suggested? Being newly diagnosed can be so stressful. I found things got easier for me as they moved along. I'm not sure of the exact answer to your question, but will investigate and you should get more responses here.

Do you have the details of your diagnosis? Grade? HR - or +? One or both breasts? Any architectural distortion noted?
I am assuming your diagnosis is DCIS, which is CONTAINED within the ducts, meaning it has not spread. When surgery is performed, clean margins is the goal, this helps minimize the chance of recurrence.
Have you met with your care team yet? Have you had any biopsies? MRI? US?

It can but rarely happens. https://www.cancer.org/cancer/managing-cancer/treatment-types/surgery/risks-of-cancer-surgery.html
I assume that you already had biopsy to confirm the diagnosis. Your onco will discuss treatment plan with you. Once you have the treatment plan, you’ll feel much better. Breast cancer treatment has advanced greatly to give us better chance to survive and to prevent recurrence. Please come back to share your concerns/questions. I hope this forum will provide you with calmness and comfort as it did for me during my early days of diagnosis. Our mentors have gone through cancer treatment themselves and everyone here is generous in sharing experience. You’re are not alone. Hugs.

I recently was diagnosed with invasive ductal carcinoma. I underwent a lumpectomy and lymph node removal, sentinel and 2 others from left side of breast. I am 2 weeks post op and am having lots of swelling at the incision site and some pain. It is not red or hot to the touch and shows no sign of infection. The swelling is almost the size of a ping pong ball and is across the entire incision site. I have my 2-week post op tomorrow to have this checked out. Is this normal?

Hello, welcome to connect. I would say this is pretty common. Not exactly normal, but I hear about it a lot. I also had this, in my case and most of the ones I know about it is seroma. A build up of serum and blood where the body pushes this to a site of injury, in this case surgical. Mine took a little time but went away on its own, as the body slowly broke it down and reabsorbed it.
I have heard of folks getting a drain for this. I am glad you are seeing the doctor tomorrow.
How are you doing since your surgery?

Yes, Barbjean I am months out from my lumpectomy and I still have days when it swells.
